Thanks for clarification, and it is also what I suspect, that would be correct from electrical theory. My personal issue is different than the OP. My wiring (original) is cleaned up nice!

I read somewhere that the internally regulated alt units have better control of the voltages. If you looked at the next gen of trucks with HEI they have internally regulated units.

Crankshaft coalition wiki site says HEI modules do not like high voltage spikes.
